Step-by-step explanation:
Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate.
Scientists have different models explaining how new species form. This includes 'Gradual Speciation' and 'Punctuated Equilibrium' models which describe the pace of speciation. Additionally, they consider 'allopatric' and 'sympatric' speciation describing the mechanisms of speciation.
The debate among scientists on how new species form revolves around different models and patterns observed in nature. Two main models of speciation that scientists explore are the 'Gradual Speciation' model and the 'Punctuated Equilibrium' model.
Gradual Speciation proposes that species evolve slowly over an extended period due to slight genetic changes from generation to generation. On the other hand, Punctuated Equilibrium suggests that species remain unchanged for many generations and then undergo rapid changes to form new species in a relatively short period.
Another aspect of the debate involves the mechanisms of speciation, including 'allopatric' and 'sympatric' speciation. Allopatric speciation involves a geographical separation of populations from a parent species and subsequent evolution, while Sympatric speciation is speciation that occurs within a parent species while in one location.

Answer:
280
Step-by-step explanation:
2/3 x 42=28
28 x 10 = 280
When rounding 4.237 to the nearest meter, we round down to the nearest whole meter.
The rounded value is 4 meters.
Here, we have,
To round 4.237 to the nearest meter,
we need to consider the digit immediately to the right of the meter place value, which is the tenth place.
If the digit in the tenth place is 5 or greater, we round up.
If it is less than 5, we round down.
In this case, the digit in the tenth place is 3, which is less than 5.
Therefore, when rounding 4.237 to the nearest meter, we round down to the nearest whole meter.
The rounded value is 4 meters.
